The utility model has the advantages that: 1. the structure is simple, 2. the operation is simple and convenient, the working hour is saved and the production efficiency is improved, 3. the maintenance is convenient and the maintenance cost is low, 4. the maintenance cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of simple in structure, easy to operate, long service life, is convenient to change conduction mouth and the low direct current submerged arc welding machine ignition tip of maintenance cost, belongs to direct current submerged arc welding machine and makes the field with ignition tip.
Background technology
CN2133398, title " automatic submerged arc welding machine ignition tip ", this device mainly is made up of led panel, quiet conductive plate, moving conductive plate, bolt nut, pogo barrel etc., and the lower end one side-prominent end of quiet conductive plate and moving conductive plate is equipped with the groove for the welding wire walking.Its weak point: the one, automaticity is low, operating efficiency is low; The 2nd, the dismounting inconvenient maintenance; The 3rd, need change whole conductive head during maintenance, maintenance cost is big.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of simple in structure, easy to operate, long service life, be convenient to change conduction mouth and the low direct current submerged arc welding machine ignition tip of maintenance cost
Design: to achieve these goals.1,1 upper-end inner diameter import of ignition tip handle and the 2 upper-end inner diameter imports of conduction mouth have the design of 45 respectively, are one of technical characterictics of the present utility model.The purpose of doing like this is: the one, in welding process in order to obtain good electrical conductivity, the inner diameter hole diameter of conduction mouth is usually only than the big 0.1mm-0.2mm of gage of wire, in order to make welding wire can successfully enter inner diameter hole, so processed 45 ° of chamferings respectively at conduction mouth upper-end inner diameter position, so just formed a welding wire lead-in groove, in like manner the chamfering on the ignition tip handle also is same effect; The 2nd, after welding wire for submerged-arc welding enters the ignition tip handle, enter the ignition tip capitiform by the welding wire lead-in groove and become welding, when changing welding wire, need not artificial again wire feed owing to processed the welding wire lead-in groove, can realize automatic feeding.2, design by being threaded between ignition tip handle and the conduction mouth is two of a technical characterictic of the present utility model.The purpose of doing like this is: the one, be threaded, and only need to carry out shirtsleeve operation when changing the conduction mouth and just can finish with a spanner, make the ignition tip handle and conduct electricity between the mouth dismounting easy to maintenance; The 2nd, because in welding process, welding wire need constantly pass through ignition tip, at this moment welding wire and the ignition tip head friction that is bound to constantly produce, time one is long, the internal diameter size of conduction mouth can increase, when increasing to a certain degree, welding wire just can not form excellent contact with the conduction mouth, the effect of conduction will descend thereupon, thereby directly influenced the continuation of welding process, just so-called current interruption is in case the phenomenon of current interruption occurs, at this moment the welder only needs the mouth of replacing conduction in time to get final product, and the ignition tip handle is fixed on above the welding machine frame, is non-damageable in normal welding use, so can need not change for a long time, long service life not only, and maintenance cost is low.
Technical scheme: the direct current submerged arc welding machine ignition tip, forms by ignition tip handle and conduction mouth, import of described ignition tip handle upper-end inner diameter and the import of conduction mouth upper-end inner diameter have 45 ° angle respectively, and ignition tip handle lower end with conduct electricity on the mouth for being threaded.
The utility model is compared with background technology, and the one, simple in structure; The 2nd, simple to operation, save man-hour, enhance productivity, when changing welding wire, need not artificial again wire feed owing to processed the welding wire lead-in groove, can realize automatic feeding, and when changing ignition tip, also can save man-hour greatly, improve production efficiency; The 3rd, easy to maintenance, no matter use which kind of ignition tip, the friction of welding wire and ignition tip keeps away unavoidable, that is to say, the internal diameter size of ignition tip is bound to increase, the frequency that this also directly causes ignition tip to be changed, and the structural design of this ignition tip can very conveniently be keeped in repair; The 4th, greatly reduced maintenance cost, changing such conduction mouth only needs several yuan cost.
Description of drawings
Fig. 1 is the structural representation of the ignition tip handle of direct current submerged arc welding machine ignition tip.
Fig. 2 is the structural representation of the conduction mouth of direct current submerged arc welding machine ignition tip.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1～2.The direct current submerged arc welding machine ignition tip is made up of ignition tip handle 1 and conduction mouth 2, and described ignition tip handle 1 upper-end inner diameter import and the 2 upper-end inner diameter imports of conduction mouth have 45 ° angle 3 respectively, and ignition tip handle 1 lower end with conduct electricity mouth 2 upper ends for being threaded.The inner diameter hole diameter of conduction mouth is than the big 0.1mm-0.2mm of gage of wire.Described sparking plug handle has groove and groove walls for 1 time, and to be shaped on screw thread and the upper end of conduction mouth be that screw thread spins and can screw off and separates, and purpose is when the wearing and tearing of conduction mouth internal diameter increase, and is convenient to replacing.
What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (2)
1. direct current submerged arc welding machine ignition tip, form by ignition tip handle and conduction mouth, it is characterized in that: import of described ignition tip handle upper-end inner diameter and the import of conduction mouth upper-end inner diameter have 45 ° angle respectively, and on ignition tip handle lower end and the conduction mouth for being threaded.
2. direct current submerged arc welding machine ignition tip according to claim 1 is characterized in that: have under the described sparking plug handle groove and groove walls be shaped on screw thread with the conduction mouth the upper end be that screw thread spins.
